摘　　要：淮安赵集矿区芒硝矿藏具有矿层单一、厚度薄、埋深大、品位高的地质特点,目前主要应用水平连通井组进行水溶开采。针对无水芒硝矿层薄,盐硝地层钻速快的特点,以及对A靶和B靶的精准要求,建立适用于无水芒硝连通井组的地质导向技术。通过对现场K50井组的应用实践表明,提高了A、B靶点的中靶精度,对后期水溶开采矿层厚度提供最大的保证,这项技术对井下盐硝等固体矿藏连通井组水溶开采模式具有较好的借鉴意义。The mirabilite deposit in Zhaoji mining area in Huai'an has the geological characteristics of single ore layer,thin thickness,large buried depth and high grade.At present,the horizontal connected well group is mainly used for water-soluble mining.In view of the characteristics of thin rock salt layer and fast drilling speed of rock salt formation,and the precise requirements for the target A and the target B,establish the geological guidance technology applicable to the connected well group.Through the application practice of the field K50 well group showed that through the advance classification and control of the target,the position accuracy of the final target is improved,and the thickness of the water-soluble mining layer in the later stage is guaranteed.This technology has a good reference significance for the water-soluble mining mode of connected solid mineral deposits such as underground salt and nitrate.
